Question: Error, (in dsolve/numeric/DAE/isolate) is not linear

Dear All,

Im trying to model a rigid body, hanging from a string. In the end I have a system of 5 Equations of Motion and with all the Initial conditions I use dsolve. It gives me the error 

Error, (in dsolve/numeric/DAE/isolate) is not linear

I know the system is not lnear but that should be not a problem. One strange thing I notice is that Maple adds these dots in some equations: (the one after 15 but please see original file)


Could this have anything to do with it? Or is something going wrong in the Matrix caclulations? Attached you find the original file, please have a look at it.

Kind regards
